5-2 Details of the Origin-point Location and Cutting Area The Location of the Origin Point Immediately After Loading Material With the CX-500/400/300, the initial origin point is determined when you load material and press the [ENTER] key. The origin point that is initially determined when you press the [ENTER] key differs according to the selection made for [SELECT SHEET] with the operation panel when loading material.
The Location of the Origin Point Immediately After Loading Material (When [AXIS ROTATE] is set to [0deg]) “ROLL” (When using roll material) The origin point is set at the location where the material is loaded, near the left pinch roller. Material Pinch Roller (0.0) Margin Depends on length when loaded “PIECE” (When using flat material) 30 mm (1-3/16 in.) Material Pinch Roller (0.
Coordinate Rotation Settings This rotates the cutting coordinates by 90 degrees. The default setting is at [0deg], and the origin point is set at the lower left of the material. Setting this to [90deg] set the origin point at the lower right of the material and rotates the text (or graphics) by 90 degrees. * Note that the coordinate axes change when rotated. Make the settings to match the program you're using. (When you are performing output using the CAMM-1 driver, set this to [0deg].
About the Cutting Area The cutting area along the horizontal plane (the direction in which the tool carriage moves) is determined by the position of the pinch rollers. The workable area spans the length between the two rollers, minus a margin of about 1 mm (about 0.04 in.) on both sides. If the material length is greater than 1,600 mm (63 in.) when a flat material has been loaded, the CX-500/400/300 determines it to be a rolled material and sets the material length to 24,998 mm (984-1/8 in.).
2 Pull out the material from the roll and pass it through the unit. Stretch taut, with no slackness. 3 Position the left- and right-hand pinch rollers as shown in the figure. Position the middle pinch roller over the grit roller that lies between the left- and right-hand pinch rollers. 25 mm (1 in.) or more 25 mm (1 in.) or more Guide lines 4 While keeping the material stretched taut, raise the sheet loading lever to secure the material in place.
7 Use the operation panel as follows to perform test feed for the material. The material is fed out by the set length. Make sure the material is not crooked. If the material is crooked and looks like it might come loose from the pinch rollers, press the [PAUSE] key, then hold down the [ENTER] key for 0.5 seconds or longer to stop material feed. Reload the material. SELECT SHEET ROLL PIECE Press [ ] or [ ] to select [ROLL]. AREA MOVE 1.0m Press [ ] or [ ] to change the value. Press [ ]. Press [ENTER].
If a pinch roller is positioned over an area where there is no grit roller, the message shown at right appears when you press the [ENTER] key. If this occurs, lower the sheet loading levers and move the pinch rollers to the proper positions above the grit rollers. Reposition the material to match this new alignment, then lift the sheet loading levers to hold the material in place.
5-6 Front Loading You can use the front-loading feature of the CX-500/400/300, which lets you load roll material at the front of the machine, by installing the sheet hanger on the front. Installing the Sheet Hanger Install the sheet hanger on the front of the machine.
